Be it known that we, JAMES C. GENTRY l juste'd upon the shaft to regulate,in a manner f the to be presently described, the stroke o and J oiiN T. BorroMLss, citizens of the l dasher-shaft.

United States, residing at Dayton, iii the ln order to transmit power from the drivecounty of Rhea, State of Tennessee, have inhaft to the dasher-shaft, we provide a novel vented certain new and useful improvements j mechanism, whichwill now be described. Sein Churns; and we do hereby declare the folcured at its lower end to the rear face of the lowing to be a lull, clear, and exact descripl standard 7 and extending upwardly, reartion of the invention, such as will enable othwardly, and laterallyT therefrom is a springers skilled'in the art to which it appertains to metal bracket-arm 1S, which, by reason o its make and use the same. lateral extension, has its u per end located This invention relates to churns, and has in a vertical plane to one si e of the standard for its object to provide a churn of the vertical reciprocatory dasher-shaft type in which the churn and its shaft may be quickly and readily disconnected from the operating 7. A bar 19 has its ends bifurcated, as at 20 and 21, and pivotally received in the bifurcation 2O is the upper end of the spring-metal bracket-arm 18, the dasher-shaft 9 being received in the bifurcation 21 of the bar and held therein for movement with this end of the bar by means of a removable pivot-bolt 21 The bar 19 is slotted, as at 22, intermediate its ends, and engaged th A further object of the invention is to provide a novel means for adjusting the length of stroke of the said dasher-shaft to suit the quantity of milk being churned. l

Tn the accompanying drawings, a side elevation of the invention. Fig. 2 is a rough the slot and pivotally connected with the bar at this point is the upper end of a connecting-ro 23, front elevation thereof. Fig. 3 is a detail which is connected at its lower end to a stud vertical transverse sectional view through 24', carried by the crank-arm 17. the upper end of the standard for the operatlt will be readily understood from the foreing mechanism, showing the manner 4of going that rotation of the drive-shaft and its mounting the dasher-shaft guide thereon. crank-arm 17 will result in an oscillation of Fig. 4 is a side elevation thereof in detail, the bar 14 and a consequent vertical reciproshowi'ng the guide swung out of operative poj cation of the dasher-shaft 9. sition. Fig. 5 is a detail perspective view of ln order that the shaft may be guided durthe oscillating bar for transmitting the power ing its reciprocatory movement, we provide a from the drive-shaft to the dasher-shaft, and guide-bracket 24, which is pivoted upon a bolt 25, which latter extends through the Fig. 6 is a detail sectional view of the drivestandard 7, adjacent the upper end thereof, and is connected shzaft of the device.

Referring more specifically to the drawat the opposite side of the ings, the numera 6 denotes a base; 7, an upsaid standard to the bracket-arm 24 with the standing standard mounted thereon. up er end of aspring-arni 26, which tends to movably hold the guide-bracket- 24 against The numeral S denotes the churn-body, and 9 the dasher-shaft working therein. the standard regardless of its movement in a vertical plane. To hold the said guide- J ournaled upon the face of the standard i adjacent the cliurn-body 8 in a suitable bearl bracket firmly in a horizontal position to Figure 1 is 'ing-bracket 10 is a shaft 11, upon which is properly guidethe flasher-shaft,wefcrminthe mounted a fly-wheel 12, having a crank-hanadjacent side of the' standard a slot 27, iiito dle 13, by means of which the shaft may be which the rear end of the bracket is adapted rotated. The opposite end of the shaft 11 to seat, it being understood, of course, that nut 14 and is shouldere shaft from the operating mechanism it is between the shoulder 15 and the nut 14 is a crank-arm 16, which is slotted, as at 17, for l only necessary to swing the guide-brackelt whic i the engagement of the said en of the shaft vertically and remove the pin 21 therethrough, it connects the shaft with the oscillating bar being understood that by, this construction the crank-arm may be ad- 19. 1t will furthermore be understood that to the fiy-wheel 12 extends beyond the corresponding side of the bracket 10 and is screwthreaded for the engagement therewith of a d as at 15.
